In 1973 Mathiessen journeyed wioth George Schaller, a field biologist, to Crystal Mountain in the Himalayas, to study the wiild blue sheep of the region called bharal. They also hoped to see the rare snow leopard, an almost mythical creature which Schaller once glimpsed on a previous visit. Matthiessen is a student of Zen Buddhism and for him this was as much an inner journey as a field trip. He succeeds well in blending the spiritual with the earthly and thisbook i an evocative accoutn of a remote and timeless place and its people.
